e IMPRQVEMENT IN STEAM-RADIATORS.

Specification forming part of Letters Patent No. 38,247, dated April 21, 1863.

To a/ZZ whom, it may concern:

Be it known that I, J. J. SMITH, of New York city, of the county of New York, in the State of New York, have invented a new and useful Improvement in Steam or HotVater Coils of Heating Apparatus; and I do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings, making part of this application.

My invention relates to a newarticle of manufacture, and has for its object the production of an ornamental radiating-coil which may be employed at a much less cost in lieu of the ordinary plain coil surrounded by an ornamental screen or ornamented surroundings; and to these ends my said invention consists in a radiating-coil, (for steam or hotwater apparatuses,) so constructed that its tubes run nearly or about parallel with each other, as hereinafter specified, with a designpainted, gilded, or otherwise producedupon the tubes of the coil, as hereinafter fully described.

To enable those skilled in the art to make and use my invention, vI will more fully describe it, referring by letters to the accoman ino" drawin s in which- Figure l is an elevation of one'ofvmy improved ornamented coils 5 and Fig. 2is an elevation of one of the old kind of radiators, consisting of a rough coil inclosed by an ornamental screen.

In Fig. 1,0 c c, &c., are the tubes of which the coil is composed, and which are coupled or connected together a-t their ends by the return-bends' b b, 85e., in such manner as to constitute a continuous conduit or channel for the passage of the heating medium. The top andl bottom pipes or tubes of the series are connected at C and D to the pipe A, which both supplies the steam and carries back the condensed steam, (according to an improvement of WV. C. Baker, made the subject of Letters Patent.)

B is an ordinary hand-wheel for operating the cock c in pipe A..

The return-bends b b, &c., are so constructed and arranged (as clearly shown) as to rest one on the other and regulate or maintain the spaces between the tubes c c, 85e., while a surrounding strap 0r band, S, at either end of the coil securely locks thc whole apparatus to- Vgether.

It will be observed that the construction of the coil is such as to dispense with the pieces generally employed to hold the tubes c o apart, while the latter are made to run nearly parallel with each other, and itwill be understood that this lastnamed peculiarity is of essential importance in the production of a design on the tubes or coil.

In the radiator shown at Fig. 2 the coil has its tubes c c, &c., running at a considerable angle with each other, or very much inclined from horizontal lines with each couple or pair of the tubes held apart by braces or block ll, tc., and the whole is held together by a band or strap, S, at each end of the coil.

I is a cast-iron screen, which surrounds the coil, and is covered generally on top with a marble slab, G. The designs of the screens I are very numerous and familiar to every one, and are much more costly, together with the coil, than one of my ornamented coils, while the latter are quite as desirable for very many places.

In Fig. 2 in the drawings I have shown the screen partially broken away to display the arrangement of the tubes of the coil.

There are made and used a great many varieties of radiators in which coils are elnployed, but in all` of them some kind of screenV or other ornamental surrounding or accompaniment is employed which renders the radiator more or less costly, so that in many instances where economy has to be practiced a great saving is effected by simply putting up a plain coil and leaving ot't' the expensive screen or other usual accompaniment. Now, by my invention the public will be furnished with .a radiator which will cost only a very little more than a plain coil and much less than the kind of radiators now furnished, while it will be nearly if not quite as ornamental as the latter, and in many instances more desirable. Thus a very great desideratum is accomplished by my improvementviz., the production of an article much needed and a saving to the public.

It will be seen that by bringing the tubes c c about parallel, or nearly so, every variety of design can be executed on the side or sides of the coil, which could be produced on a plain what I claim as new, and desire to secure by Let-ters Patent, as a new article ofmanufacture, is

An'ornamented coil-radiator, substantially as hereinbefore set forth.

. In testimony whereof I have hereunto set my hand and afiixed my seal this 7th day of May, 1862.
